HEEL-BUILDING MACHINE.

To all whom it may concern:

'Be it known that I, ALEXANDER A. HUD- SON, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Heel- Building Machines, of which the following is a specification.

This invention relates to improvements in heel building machines and particularly to heel building machines of the type disclosed in my United States LettersPatent Number 1,156,842.

An object of my present invention is to produce means for quickly and uniformly adjusting the clamps mounted on the rotatable clamp support to receive heel'blocks V of diiierent sizes.

v A further objectis to produce means for adjustingthe clamp jaws predetermlned amounts to receiverough heel blocks of cermin sizes.

"These and other objects are attained in the device described in the following specification and illustrated in the accompanying drawings in which:

Figure l is a side elevation of a heel building machine having a clamp setting device embodying my invention cooperating therewith. Fig. 2 is a fragmental elevation showing my clamp setting device cooperat 7 ing with the clamps mounted on'the rotatable clamp support. .Fig. 3 is a diagrammatic viewillustrating the operation of the clamp setting device embodying my invention.

The heel building machine disclosed in 'my above-mentionedpatent and illustrated in cooperation with the clamp setting device constituting the novel subject matter of my present application, comprises a frame 4, a

blank assembling device 5, a rotatable clamp support 6, and a series of clamps 7 mounted on the clamp support. 'Adjacent to the clamp support and surrounding the blank assembling device 5, is a table 8 having thereon a series of bins 9 for the various sizes of heel blanks used in the construction of heel blocks. 7

Adjacent to the back of the table, and secured to a board 10 covering the bins, is the clamp setting device embodying my invention. having a series of pins 12 reciprocally mounted in holes extending transversely thereof. The outer ends of these pins are provided with knobs '13 by means of which Specification of Letters Patent.

This device comprises a frame 11 pins 20 and 21.

Patented Mar. 28, 1916.

Application filed August 13, 1915. Serial No. 45,398.

the pins may be reciprocated to move their inner ends toward or away from the periphery of the rotatable clamp support. Each of the clamps mounted on the clamp support, 'is provided with two. relatively movable jaws 14: and 15, the jaw 14 being operatively connected with the clamp operating handle 16, with the jaw 15 adjustably mounted to be moved toward or away from the jaw 14, by means of an adjustment screw 17 passing through a lug 18 formed on the base 19 of the clamp, and engaging the rear face of the jaw. In the projecting end of the screw threaded shaft are two pins 20 and 21 mounted in bores located at right angles to one-another. The clamp setting device is located on the board 10 in such a position that its pins 13 will be engaged by the ends of the pins 20 and 21 in the ad clamp support 6 is rotated, as shown in Fig.

This causesrotation of the adjustment screwof each clamp through a quarter of a revolution thereof, each time one of the pins 13 of the clamp setting device is passed. The action of the cooperating pins 13, 20 and 21 is therefore like that of a rack and pinion in which the rack imparts rotary motion to the pinion as it passes over it. The amount of rotation imparted to the adjustment screw is governed by the number of pins 13 which have been moved to engage the pins 20 and 21, so that the efiect produced is that oi increasing or decreasing the length of the rack over which the pinion comprising the screw threaded shaft and its pins 20 and 2l, moves.

In the machine embodying my invention, the screw 17 is provided with screw threads having a certain number of threads per inch,

as for example 16, so that for each engageto the direction of movement of the clamp support 6. The distance of adjustment of the jaw 15 each time it passes the clamp setting device, will therefore depend upon the number of pins 13 which have been moved into the path of movement of the In Fig. 2 of the drawings, three of the pins 13 have been moved to be engagedby the pins 20 and 21, so that the amount of adjustment afforded by ment of the pins 20 or 21'with each pin this'arrangement, with 16 screw threads per inch as in the above example, would-give an adjustment of 3/64; of an inch of the jaw 15. In order to adjust the jaw 15 toward the jaw l i counter clockwise rotation of the.

support 6, as viewed in Fig. 1, would be necessary, while to adjust the jawin an opposite direction, clockwise rotationthereo'f is necessary.

I contemplateemploying any cooperating rack and pinion construction in which the rack is provided with removable teeth, as shown in the drawings illustrating an embodiment of my invention.

Havingthus described my invention, what I claim is: V i

1. In a heel building machine the combination of a movable clamp support, a series of clamps mounted on the clamp support, and a single clamp setting means located adjacent to the support, to be engaged by the clamps when the support is moved, whereby the clamp jaws will be uniformly adjusted to receive heel blocks between them, said means being removable from engagement with the clamps to permit unobstructed movement of the support after the clamps are adjusted.

2. Aheel building machine comprising a movable clamp support, a serles O'lf clamps mounted on the clamp support, and adjustable means located adjacent to the support,

to be engaged by the clamps when the support is moved. whereby the clamp jaws willbe uniformly adjusted predetermined distances apart when the clamps are released,

said means being removable from engagement with the clamps to permit complete and unobstructed movement of the support after the clamps are adjusted.

3. In combination in a heel building machine, a seriesof clamps, a vertically rotatable wheel adaptedto mount the clamps on itsrim and a clamp settingdevice mounted adjacent to the wheel, and consisting of Copies of this patent may be obtained for five cents each, by addressing" the Commissions a rack having movable means for increasing or decreasing its length, each of said clamps having an adjustable jaw, and means for adjusting said jaw, saidmeans being located adjacent'to the clamp setting device and having a toothed end adapted to engage the rack, whereby the jaw will be moved t0 adj ustedpositions .when the wheel is rotated to bring the teeth and rack into and out of engagement with one another.,

l. In a heel building machine, a series of clamps, a rotatable clamp support for mounting the clamps and: a, clamp "setting" device located adjacent to the clamps, each to form a toothed pinion, said clampsetting I device consisting of a series of movablepins forming arack adapted to be engaged by the pins of the adjacent screw to rotate the screw. I

A heel building machine comprising a movable clamp support, a series of'clamps V mounted on the clamp support, li aving a clamp jaw and an adj ust-able jaw,jand ameans located adjacent to the support and adapted to be rotativcly connected with theiadju'st 1V able jawof each clamp when the support is rotated, to adjust the adj ustable jaws, said means being adjustable tdadjust thejaws various desired amounts, and removable from operative connection with the adj ustable jawsto permit the complete and unobstructed movement of the support,

In testimony whereof, I have hereunto subscribed my name thistenth day of August, 1915,
